This is a problem i've had since the very first day of making AMV, the background music of Dragon Ball Z for example just interrupt with the music i chose, it makes the video sounds weird.
Im currently using Sony Vegas 14, hope all the experienced people can help me

Unless the audio track is 5.1, there really isn't a good way to do that. If the audio is 5.1 most of the dialog will be in the front center speaker and usually there is no other music or sounds set to that channel.

I know this thread is almost a year old and it's not likely that the OP will see this post, but given how much of a Holy Grail this kind of separation has been for the longest time (as the other posts on this very thread indicate), I thought I should mention this site that I discovered recently:

The claim is that using AI techniques results in more intelligent separation than just the usual methods of channel mixing and the like. Naturally, this will still work better on some sources than on others.
